Beit known that I, BENJAMIN S: PEARD, a

citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, city andState of NewYork, have invented certainhew'and useful Improvements in Wheels for Roller-Skates, of which the fol ,lowing is a specification accompanied. by gdrawings.

This invention relates to wheels, but more particularly to wheels for roller-skates, although the same construction may be used for wheels for other mil-poses.

The objects of the invention are to improve upon the construction of wheels for roller skates and other purposes, making them more rigid, with increased strength, lightness, and

simplicity of parts, which may be readily taken tail sectional view on the line apart and put together.

Further objects of the invention will hereinafter appear; and to these ends the invention consists of a wheel for carrying out the above objects embodying the features of construction,combination of elements, and arrangements of parts, substantially as hereinafter fully described and claimed in this speci fication and shown in theptollowing drawings, in which- Figure 1 is a side view of a wheel emho'dying the invention. on the line 2 2 of Fig. 1. Fig. 3 is a detail view, partly broken away, of a portion of one form of a tire. Fig. 4 is adetail view, partly broken away, of a section of a wheel, showing a modified means for maintaining the tire securely in position on the rim.

5 5 of Fig. 4t. Fig. 6 is an enlarged longitudinal sectional view taken through the hub with the side parts broken away and the ball-bearing moved.

Referring to the drawings, A represents a metallic hub provided with outside flanges or projections B, spaced inwardly from the outside edges of the hub. As shown, the outer portions of these flanges or projections have plain surfaces, while the inner portions are provided with fillets to add strength and rigidity to the construction. The hub is provided with an inside flange C, forming ball-races on each side thereof for the ball-bearing. The outside flanges or projections B aiford abutnientsfor the metallic side parts I), which form the sides of the wheel. The portions of the hub A between the flanges B and the outside edges of the hub are shown as screwthreaded at E, while screw-threaded nuts or I flanges I to form the 2 is a section view Fig. 5 is a de washers F cooperate with the screw-threaded portions of the hub for clamping the side parts D firmly against the flanges B to hold them in position. In this instance the clamp-- ing members F are shown in the form of washers provided with notches G for a key.

Preferably the wheel side parts D are in skeleton form for lightness, having the spokes H and t-heoutward endliaring portions. or rim of the wheel for the tire J, which is preferably of rubber. As shown in Fig. 3. the tire may be provided with inwardly-extending tongues K, having apertures L, while the screws 0, as shown, pass through the outer ends of the spokes and through the apertures of the tire, thereby iirmly holding the tire in position. The screws 0, as showh, are provided with nuts P. in Fig. '-l the tire J is not provided with a tongue K; but the rims if of the wheel have portions pressed inwardly, as at Q, which portions tightly grip the tire and hold it in position.

The wheel is provided with a ball-bearing,

' and, tS:SllO\VI'l, the axle It is preferably screwthreaded and is provided with the cones S and holdinprnuts T. Between the cones and the inner flange C of the hub are arranged the balls U.

According to this invention it will be seen that the wheel comprises a. ball-bearing hub stamped out to form lilleted spokes, hub, and

rind, said side parts being adapted to fit over the threadedends of the hub and being s6- cured against the shoulders on the hub by the nuts which engage with the threads on the hub ends. The side parts in accordance with this invention are assembled with their spokes opposite each other, and a rubber tire is our braced between the rim portions of the side parts. The tire-securing means shown and described are provided for holding the tire in place, and, as shown and described, means arev also provided for bolting together the opposite spokes of the side parts at points in side of the tire to bind the side parts togetl'ier so that the spokes in longitudinal section have inwardly-tnrned outlines, as fully disclosed in Fig. 2 of the drawings.

This whole improved construction is light, strong, and compact. The hub being all in one piece adds strength to the construction and being provided with the flanges B afiords a secure means of holding the side parts in position.

According to the construction of this wheel it will be seen that there are few parts to become loose, and in a wheel for a roller-skate used upon the modern two-wheeled racing- 1, skate it is absolutely necessary that high speed 2 may be attained without loosening of the parts of the wheel and without the tire coming off. This construction provides against these emergencies. constructed that great side thrusts may be sustained without injury to the wheel, and

this improved construct ion especially provides against this danger.

Obviously some features of this invention maybe used without others, and the invention may be embodied in widely varying forms.

Therefore, without limiting the invention to the construction shown and described nor enumerating equivalents, it is desired to claim and obtain by Letters Patent the following:

A wheel, comprising a ball-bearing hub It is necessary that the wheel be so 5 having threaded ends, a shoulder near each i cud o the hub, and a central circumferential gro e, nuts to engage the said threaded ends, I side parts stamped out to form lilleted spokes, l hub and rim, said side parts litting over said threaded ends and being secured against said shoulders by the nuts engaging with the threads on the ends of the hub, the side parts being assembled with their spokes opposite each other, a rubber tire embraced between the rim portions of the side parts, tire-securing means for holding the tire in place, and j means for bolting together opposite spokes of l theside parts at points insideof the tire to bind 1 the side parts together, so that the spokes in longitudinal section have inwardly-turned outlines.

In testimony whereof I have signed this specilication in the presence of two subscrib- 1 ing witnesses.
